There are several information's of immense importance already given in the question. Based on the given information's the answer to the question can easily be determined.
Distance covered by the bicycle = 5000 meter
Time taken by the bicycle to reach the distance = 500 second.
Velocity of the bicycle = Distance / Time taken
= 5000/500 meter/second
= 50 meter/second
So the velocity of the bicycle is 50 meter per second. I hope the procedure is clear enough for you to understand. In future you can always use this procedure for solving similar problems.
Answer:
The value is 
Explanation:
From the question we are told that
The initial speed is 
at a distance of 
The final speed is 
at a distance of 
Generally from the kinematic equation we have that
=> 
=> 
=>
The negative sign shows that it is decelerating
First take note that you're figuring 10am and 1pm. Their temperatures are 77 degrees and 83 degrees
To solve subtract 83-77=6
So it rose 6 degrees.
The answer is two (4 -3)
Zero is not a SF
